1. I am interested in capabilities/limits of ActiveMQ. Is there a published report that give ActiveMQ performance numbers? Example: Messages per second as a function of message size?

2. If I wanted to do my own ActiveMQ performance test is there a standard JMS (activeMQ) load/stress test tool/software out there? Of course I can write one myself for the N th time. So does anyone know of a tool that does JMS load/stress testing?

Just to let you know. The maven-activemq-perf-plugin has been updated recently to also provide support for

- consumer/producer throttling (AMQ-3186)

- message selector in the consumer (AMQ-3280)

- message headers (AMQ-3280)

- fixed broken transaction support (AMQ-3283)

The last of the fixes still needs to be merged to the trunk, the others are available on the trunk version already. The plugin documentation got updated as well (docs update for AMQ-3283 still outstanding but will be done in the next day or two).
